URL: https://github.com/llvm/llvm-project/commit/a1303b23c9de6ef6d667aa923ec266ca4a0334e7 DIFF: https://github.com/llvm/llvm-project/commit/a1303b23c9de6ef6d667aa923ec266ca4a0334e7.diff LOG: clang/AMDGPU: Define macro for -munsafe-fp-atomics The HIP headers want to use this to swap the implementation of the function, rather than relying on backend expansion of the generic atomic instruction.
